66413955 divided by 724 
The aim is to understand the frequency of 724 in 66413955.

Let's proceed to step 1:
724 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 724

On to step 2:
724 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 724

Going ahead to step 3:
If we divide 664 by 724, we get 0 and a remainder of 664.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 664, we end up with 664.
Include the next digit (1) from the dividend after 664, then repeat: 6641 / 724

On to step 4:
724 goes into 6641 9 times with a remainder of 125.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 6516 from 6641 to get 125.
Grab the next digit (3) from the dividend, add it to 125, then carry on: 1253 / 724

Let's proceed to step 5:
When dividing 1253 by 724, we get 1 with a remainder of 529.
Write down 1 as next digit of the result. 
Result so far: 91.0
If we subtract 724 from 1253, we get 529.
Grab the next digit (9) from the dividend, add it to 529, then carry on: 5299 / 724

Moving on to step 6:
When dividing 5299 by 724, we get 7 with a remainder of 231.
Put 7 as the next digit of the answer. 
Result so far: 917.0
The remainder is 231 after subtracting 5068 from 5299.
Take the next digit (5) from the dividend and append it to 231, then repeat: 2315 / 724

Going ahead to step 7:
2315 divided by 724 is 3 with a remainder of 143.
Put 3 as the next digit of the answer. 
Result so far: 9173.0
If we subtract 2172 from 2315, we get 143.
Fetch the next digit (5) from the dividend, attach it to 143 and continue: 1435 / 724

Let's proceed to step 8:
The number 724 fits into 1435 1 times, leaving a remainder of 711.
Record the quotient 1 as the next digit in the result. 
Result so far: 91731.0
If we subtract 724 from 1435, we get 711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

On to step 9:
724 goes into 7110 9 times with a remainder of 594.
Put 9 as the next digit of the answer. 
Result so far: 91731.9
The remainder is 594 after subtracting 6516 from 7110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Moving on to step 10:
5940 divided by 724 is 8 with a remainder of 148.
Write down 8 as next digit of the result. 
Result so far: 91731.98
Subtract 5792 from 5940 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 11:
724 can be fit into 1480 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 91731.982
Subtract 1448 from 1480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
If we divide 320 by 724, we get 0 and a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 91731.982
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 13:
724 goes into 3200 4 times with a remainder of 304.
Use 4 as the next digit of our solution. 
Result so far: 91731.98204
The remainder is 304 after subtracting 2896 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 14:
724 goes into 3040 4 times with a remainder of 144.
Put 4 as the next digit of the answer. 
Result so far: 91731.982044
Deduct 2896 from 3040 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

In conclusion, the division gives 91731.982044 with a balance of 1.44e-05.
